Description

The topological defects which are predicted to arise when the universe undergoes spontaneous symmetry breaking can decay producing dark matter particles, this alters the standard freeze-out process. Consequently this means that one can significantly weaken relic density bounds on a dark matter model by introducing defects, to showcase this I'll consider the effect of the mechanism on the Inert Doublet Model.
